I have been the Head of Data Science at a startup and am currently run data science at a large corporation. My work spans academia and industry. I am experienced as both an IC and a leader in the Data Science/Machine Learning/Artificial Intelligence space. I work on big data problems, forecasting and predictive analytics and simulation.

I have a PhD in Computer Science and Civil Engineering. I have a strong interest in simulation (real time and physics simulations) and was for a time a Research Fellow in a top-level mathematics department where I worked on Bayesian probability.

Some of my work is visible on my website, www.dkgrdatasystems.com.

While I am very interested and experienced in R&D I also work on production systems. I have extensive experience in both SaaS and hardware products.

SEEKING WORK | London, UK | Remote

I am an experienced consultant who works to convert hard, tech related research problems into deliverable products and, ultimately, ROI for your business.

I have worked extensively in industry and in academia. I mainly work in Data Science/AI/ML but am flexible.

Some examples:

- My PhD combined Machine Learning and AI with scientific computing techniques (e.g. Finite Element Analysis) and probability theory.

- I have built and delivered full stack applications (e.g. React and FastAPI) for Data Science applications.

- I have worked extensively on real time 3D software for games and other interactive simulations.

- I have helped to deliver an AI strategy and roadmaps, translating what is possible into realistic deliverables.

Some areas I have worked in that may interest you: Time series forecasting, time series anomaly detection, Computer vision, Finite element analysis, 3D modelling and simulation, Probability and information theory, Neural Networks

Some of my tech: Python (e.g. Numpy, Tensorflow, FastAPI), C, C++, C#, Java, Databases (SQL, NoSQL), Web Development (React, Javascript, HTML, CSS), Node, Cloud (Azure, AWS, Docker)

> Lights exist, though.

And pretty powerful ones, too. I remember the time when we had a very light winter and construction work didn't stop for that season. A building some 100 meters from my grandparents was being finished, a lot of roof work was happening. They had a light on that roof - when they turned it on in the middle of the night, my grandfather's room was lit as if it was just an overcast afternoon. I can only imagine that for the workers there, it felt like high noon on a cloudless summer day.

dgr582systems · 4 years ago

Not sure about other countries, but in Australia powerful construction lights are referred to as ‘day makers’ (and for good reason!).

> I wouldn't be surprised if the business had been able to pay money to Google to be able to check reviews

There is no way to do this that I can find documentation of on the public internet. You'd think if it were possible, someone would have written a howto guide. Personally, I'm deeply skeptical that any such mechanism exists. The revenue it would generate would be negligible and the potential for reputation loss significant.

dgr582systems · 5 years ago

I don’t know how they did it, but a doctor surgery near me (UK) had a large number of negative reviews up for several years. About one week ago, I looked and they now have one single 5 star review. So, anecdotally, there is at least some way to get the reviews removed.

> It’s my belief that it boils down to a few things: - self learning - dedication

And luck especially with respect to your health and the health of those around you. It's harder to invest in yourself when you are a primary caregiver to a relative.

It's this argument that makes me wonder how anybody can be opposed to some form of universal health care. I heard somebody ask this question once and it's stuck with me: how would you organize society if you knew you would be reborn but have no idea into what situation.

dgr582systems · 5 years ago

The idea (how to organise society if you won’t know your position within it) is discussed extensively by philosopher John Rawls. It is called either the “Original Position” or “veil of ignorance” thought experiment. The idea itself goes a little further back, as discussed in the linked wiki article.

Telescopes are not typically "do nothing. I am not aware of the details of Arecibo, but the big telescope in Greenbank has a paint crew work for 8 hours a day for multiple weeks each summer. And after several years the entire telescope is repainted and they start all over from the beginning. During the day time hours when the paint crew the is working the telescope can not be moved to point at objects, but is still taking data in the form of drift scans, recording whatever passes through the field of view of the telescope. A whole bunch of pulsars has been found that way.

dgr582systems · 5 years ago

To clarify, I only meant that the telescope has not been maintained (do nothing) lately as per the article. My fault for not writing more clearly.

As you say, it would be a lot of work to maintain if they wanted to keep Arecibo running.

I had the same thought when my 10 year old showed me the games he plays on Roblox. Absolutely awful graphics, gameplay, "story", etc, but they are _obsessed_ with them.

dgr582systems · 5 years ago

I think part of it (as some other comments have alluded to) is that maybe the low quality production brings the kids closer to it because they feel like they could possibly build something if they wanted to. Or that someone like them built the game they are playing. It’s perhaps more relatable than some ultra polished AAA title.

Constant painting is also a sign of efficiency.

Rather than a large number of people painting it for a small period of time, which requires a startup and close down overhead; they have instead resourced it so that they can keep a small number of people employed permenantly who accumulate expertise and minimise the mobilisations costs.

dgr582systems · 5 years ago

Agreed, but it is still more expensive in terms of direct costs than ‘do nothing’ which seems to be the case for the telescope.

Whoever downvoted me, thanks a bunch. Not sure why.

Running a team of painters still costs more than nothing. The cost of painting doesn’t cover the cost of ongoing inspections for metal fatigue etc etc. Engineering reviews, government oversight and so on.

Large bridges, especially with vehicle traffic, vibrate quite a lot and this is causes major ongoing concerns with fatigue, which means extensive monitoring along with the painting. More costs (not saying it’s unjustified).

Keeping a team going is efficient as you say, but more expensive than nothing.

It really depends on the structure. Giant steel objects are much harder to keep intact, to the point where non iconic objects are easier to replace once than maintain for 100+ years.

dgr582systems · 5 years ago

Like the (iconic) Sydney Harbour Bridge which requires continuous repainting. It’s very expensive to maintain.
